A UNITED 4- STA'rEs PATENT'OFFI GEORGE w. HARRIS, `or ELrzARErH, NE ""JERsEtYg v 3 f IMPROVEMENT IN eAs-,RlaToRi-s y* Speciiication forming part of Letters Patent No. 60,183, datediliecemb` 4, i

To all whom fit mag/' conceru:

Be it known that I, G. W. HARRIS, of Elizabeth, in the county of Union and State of New Jersey, have invented anew and useful Improvement in GasRetorts; andI dohereby declare that the following is a full, clear, and eXact description thereof, which will enable those skilled in the art to make anduse the same, reference being had to the accompany# ing drawings, forming part of this `specification, in which- Figure l represents af transverse vertical section of this invention. Fig. 2 is a horizontal section of my superheater, the line w, Fig.` 1, indicating the plane of section. Fig. 3 is a similar section of my retort, taken in the plane indicated bythe line y y, Fig. 1; y Similar letters of reference indicate corresponding parts.

This invention consists in aretort made of clay or other suitable material, and provided with return-passages, either built into it afterit is made orformed into its bottom while itis manufactured, in such a manner that steam passed through said passages will be superheated and distributed through the incandescent coal placed in the retort.

It consists, also, in a superheatermade of {ire-clay or other suitable material, to be used in combination with the retort, in such a manner Athat the steam is superheated before it e11- ters the retort, and prevented from cooling the same, and, furthermore, the effect ofthe steam on the incandescent coal in "the retort is increased. v

A represents a retort, of 4clay or other suitable material, in the bottom of which are built or formed a series of return-passages, a, through which steam is conducted. Vlhile` passing through thesepassages the` steam is superretort by means'of a large number of l tomoftheretort. `Afterhavingpassed,through heated, and it is distributed throughout the as shownin Fig.3. M In order to superheatthesteam before it;4 passes` into the passages a, a suitable Superf` heater, B, may be built into `or introducedi the setting of a bench of` retorts.` f .This su heater is made of lireclaygorwother suita le material, and it is providedwith returnpa sages b, similar tothe passages a inthebotholes in the inner end of 1 said return-passages,

the Vsuperheate'r `the steam is admitted into the` passages'a, whence it is distributed through the incandescent coal inthe retort. `Bythis arrangement. the; temperatureof `the steaml` raised to such ia degree before fit reaches `the retort that said retort will not be cooled dow and, furthermore, its nal temperature is muc higher than it wouldbewithout the supe heater, and its decomposing, effect is increase In the manufacture of illuminatingfgas, t retort A will be filled with anthracite coal, an by passing superheated steam through "t same hydrogen gas will be produced, which passed through another" retort -iilled with b1- tuminous coal. It is obvious, however, nthat i my superheating attachmentmay be used with1 advantage in thelordinary. process of facturing gas, or in other` branches of `m facture. y j I claim asnew and desire to secure` ters Patent- Y 1i l The @combination of the fireclay ,retor` `A and superheater ,B,..when;arranged as he specified, to inject the superheated `steam `at the bottom of the Vloedfof.;incandescentcoal.
